SPRiNG-BUMPIER FOR anronomnns.

' Application filed September To all 1071 am it may 0071 Pern- Be it known that I. VILLIAM G. Gox, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio. have invented certain new and useful Improvements in Spring-Bump v be readily assembled and attached to 'the fender irons and frame of certain types of automobiles, and also adapted to cushion and absorb shocks and impacts without breakage of the fender or injury to the vehicle.

In the accompanying drawing, Figure 1 is i a plan view of my'improved bumper mounted upon the front end of an automobile, and Fig, 2 is a front View of the same parts, Fig.

3 is a side viewand vertical. section on line 3--3 of F1 1. Fig. 4 IS a cross section on line 4-4 0 Fig. 3, of a portion of the channel frame of the vehicle, showing one bracket member of the bumper bolted thereto.

The bumper comprises a narrow and relatively long spring impact has 2 which is doubled back at each end to provide separate spring arms 3-3 of sweepin curvature adapted to extend inwardly an rearwardly toward the channeled side members 4 of the vehicle frame so that the'perforated extremities 5 of arms 3 may bebolted directly'to the straight middle portions 5' of a pair of sup-. porting bars or brackets 6 of spring metal iaving curved front portions 7 adaptedto overlap and bear against each other at the rear side and middle of the front bar 2. The overlapping ends 8'of supporting bars 6 have parallel slots 9 adapts to register with a bolt opening in front bar 2, and a bolt 10 unites the three bars together at this meeting oint. A shock or blow centrally on the umper flexes all three bars of the bumper inwardly and under severe shocks the slots permit the rear bars to move within limits in respect to each other and the bolt, thus preventing a brealrat the union. The slots also permit the supporting bars or brackets 6 to spring or be spread apart or brought nearer to each other at their inner ends 12 where engaged with frame members 4, thus adapting' the bars to be readily fitted and at- Speclflcation of Letters Patent.
